WATER-MOTOR.

Speccaton of Letters Patent.

Patented Jan. 27, 1920.

Application led April 911, 1919. Serial No. 291,549.

To all whom it may concern:

Be it known that I, lvnnson' D. Humans, a citizen of the United States,residing at Kirkwood, in the county of Dekalb and State of Georgia, haveinvented certain new and useful Improvements in later-Motors, of whichthe following is a specification.

rlhis invention relates to improvements in hydraulic motors and has forits object to provide a motor in which power is obtained from thevertical oscillation of a pair of arm carried buckets which arealternately lled with and emptied of water deposited therein when thebuckets assume an elevated position.

Another object is the provision of a motor of this character in whichthe pivoted buckets are locked in elevated position until apredetermined' quantity of water is deposited therein whereupon theweight of the liquid is utilized to release and permit the bucket todescend under the weight of the liquid contained therein.

Another objectvisthe provision of means facilitating the automaticrelease of the bucket upon the reception of varying predeterminedquantities of liquid so as to vary the power developed by the motor andthereb v economize the consumption of water when the motor is carrying arelatively light load.

Vith these and other objects in view as will appear as the descriptionproceeds the invention comprises the novel features of construction,combination of elements and arrangement of parts which will be morefully described in the following specifica.- tion and set forth withparticularity in the claims appended hereto.

Figure 1 represents a side elevation of the improved motor,

Fig. 2 represents a vertical sectional view on the line 2-2 of 1, and,

Fig. 3 represents an enlarged detail sectional view through the tank,bucket and valve controlled thereby.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several viewsthe numeral 5 indicates a supporting base carrying an upright framestructure consisting of a series of vertically disposed beams 6 to whichthe cylinder supporting plates 7 are attached.

A series of horizontally disposed cylinders 8.' are; rigidly supportedfupon. the plates 7 and the cylinders are arranged in pairs, thecylinders of each pair being arranged in superposed relation andprovided with reciprocable pistons 9 carrying rods 10. rl`he lowerpistons of the opposed pairs are connected by the rods 10 and likewisethe upper cylinders of the opposed pairs and the adj acent surfaces ofthe rods, which latter are preferably offset as illustrated in Fig. 1,are formed with gear teeth which mesh with pinions 11 carried by a powershaft 12 journaled in bearings 13 adequately supported upon the plates 7and constituting spacing elements. The shaft 12 is rocked back and forthby the mechanism to be hereinafter described and imparts reciprocalmovement to the rods 10 through the gears 11.

The frame structure 6 supports an elevated tank 14 preferably ofcylindrical form and arranged horizontally. A main supply pipe 15adjacent to which the motor is arranged is connected by a branch pipe 16with the medial portion of the tank 14 and the end wall 17 of the latteris provided with tubular extensions 18 having iianged inner terminals 19arranged internally of the tank 14 and constituting seats for valves 20.Each valve is pivotally supported at 21 internally of the tank 14 and isadapted to cooperate with the seat 19 to control the admission of waterto the extensions 18. Each valve 1s connected with a jointed rod 22which is eX- tended through the end wall 23 of the eX- tension and isconnected with the lower terminal of a trip arm 24 pivotally secured toand depending from a supporting rod 25 rigidly supported upon the top ofthe tank 14.

The rock shaft 12 nonrotatably supports a sleeve 26 confined between thetwo intermediate brackets 13 and carrying integral radially projectingarms 27 which are preferably arranged at an angle of approximately 90Oto each other and are provided terminally with forks 28.

Laterally projecting trunnions 29 carried by each bucket 30 arepivotally mounted .adjacent the terminals of the forks 28 and thetrunnions are arranged out of line to the diametrical plane of thebucket so that the latter normally tilt inwardly, except that they arecounterbalanced bv adjustable weights 31 carried on outwardly projectingarms 32 rigidly secured to the outside of the bucket. The top of eachbucket sopen and,

when elevated, is disposed directly under the discharge end of the spout33 communicating with each extension 18 whereby water is discharged intothe bucket when the valve 20 is open. However, the valve is normallyretained in closed position by the tension of a spring 34 confinedbetween one of the supporting brackets for each extension 18 and the arm24, the latter' being engageable by a rod 25 carried by the terminals ofthe forks 28 whereby the valve is automatically opened as the bucket andarm approach the limit of their upward movement.

When the bucket 30 is empty, the force exerted by the weight 31 issufficient to counterbalance the bucket 30 and retain the latter inoutwardly and downwardly inclined position so that the latch 36 carriedby the inner portion is engaged behind a. keeper 37 carried by theterminal of the tank 14.

In this manner, as the bucket moves upwardly to a position underneaththe spout 33, the latch 36 is engaged behind the keeper 37 and thebucket is thus held in elevated position until a suiiicient quantity ofwater has been deposited therein to overcome the weight 31 and tilt thelatch 36 out of engagement with the keeper 37 thereby rcleasing thebucket and permitting the latter to move downwardly under the weight ofthe water contained therein.

The bottom of each bucket is provided with a discharge opening 38 overwhich is arranged a pivoted flap valve 39 normally retained in closedposition by gravity and adapted to be automatically opened as the bucketapproaches the limit of its downward movement by engagement with anupstanding lug 40 carried on a platform 41 upon which the bucket issupported when in its lowermost position.

In operation, the tank 14 is supplied with water by the supply pipe 16and assuming thatvthe parts are in the position shown in Fig. 1, the rod25 is engaged with the right hand arm 24, thereby retaining the valve 20associated therewith in open position and i permitting the liquidcontents of the tank 14 to discharge into the right hand bucket 30. Asthe weight of the contents of the bucket 30 reaches a predeterminedvalue the weight 31 is counterbalanced and the latch 36 tilted out ofengagement with the keeper 37 thereby releasing the bucket andpermitting the latter to move downwardly under the weight of the watercontained therein. As the right hand bucket and arm descend the rockshaft 12 is rotated in a clockwise direction moving the pistons 9 in theupper cylinders to the right and producing an opposed movement of thepistons in the lower cylinders and moving the left hand arm 27 and emptybucket carried thereby to an elevated position. As the 27 in theposition shown in dotted lines inv Fig. 1 and the parts are retained inthis position until the left hand bucket is filled and the weight of itscontentsv counterbal ances the weightv 31 thereby releasing the latchand permitting the bucket to move downwardly, such movement edectingrotary movement of the rock shaft 12 in a counter-clockwise directionand effecting an opposite movement of the pistons 9. If preferred, thecylinders S may he provided with air inlet valves (not shown,) throughwhich air is drawn during the suction strokes of the pistons 9 andduring the subsequent compression strokes of the pistons the air isdischarged through pipes 42.
